Cerebral Cascades
Saturday, March 31st, 2007 5:10 pm
Written by: stevesie
The brain is one of the most profound networks we can study and implements information cascading in a unique framework. The brain is a network of many neurons that provide one-way signals to each other, similar to the linear model presented in class. Neurons signal other neurons to fire by releasing neurotransmitters at […]

In the 1960’s Stanley Milgram performed an experiment where subject individuals were given a letter and asked to send this letter to an individual unknown to the subject through a chain of personal acquaintances. The result, that these letters flowed a chain of weak personal acquaintances, was used by Mark Granovetter in “The Strength of […]

The above link goes to a short series of posts on one of Scientific American’s seminar blogs. Contributors review and discuss an article by Kee et al. that appeared in Nature Neuroscience on Feb. 4, 2007. The name of the article is “Prefrontal incorporation of adult-generated granule cells into spatial memory networks in […]

Basics of Neural Network

Written by: ajg43
The field of neural networking is today being explored rapidly. As Stergiou and Siganos (http://www.doc.ic.ac.uk/~nd/surprise_96/journal/vol4/cs11/report.html) point out, research had been nearly halted in the field for nearly three decades based on a misconception regarding the ability of a model regarding the mammalian system of vision and its ability to represent different shapes. Until […]

Multi-Agent Modeling: Games on Networks
Monday, March 12th, 2007 2:55 pm
Written by: apippag
In class we alluded to the fact that a computer simulation is one method to show that the results of Network Exchange Theory could be replicated from probabilistic behavior rules enacted by computer programs. Not surprisingly there this method of computer simulation can be extended to explore a variety of other social phenomena. […]

Game theory is a concept that applies to not only humans but also to any biological population in the world. It has been used since the beginning of time, starting with the first species to inhabit the earth: viruses. In this article, two scientists undergo experiments to test their predictions that viruses have a […]
Social Network’s Healing Power Is Borne Out in Poorer Nations

Modern medicine and technology has undeniably made great advances for us–those lucky enough to enjoy its benefits. We now live longer and healthier lives, no longer needing to worry about many once-deadly diseases. We are able to screen ourselves and even our potential children for genetic illnesses. We are so optimistic about medicine that […]
The Economics of Information Security

Written by: cosmohr
A recent paper by Ross Anderson and Tyler Moore, “The Economics of Information Security: A Survey and Open Questions,” brings together the seemingly disparate fields of security and economics to discuss the reasoning behind security decisions. They provide examples such as why individual PC owners choose to install anti-virus software and why large banks choose […]

(Note: Knowledge of C# / Java / C++ is recommended.)
The beauty of neural networks is that they’re inherently generalized with respect to inputs and outputs. Simply put, there is no type of neural network dedicated to one particular task. While there are many implementations and algorithms that can be used to create a neural network, they can […]
